[0016] According to the present embodiment, a steering input device 100 can be provided, which includes a steering shaft 110, a rotor 120 coupled to the steering shaft 110 and having a spring 123 with a circumferential gap space 123c formed between both ends thereof, a first support member 130 coupled to the rotor 120, positioned in the gap space 123c, and circumferentially supported by both ends of the spring 123, a housing 150 to which the steering shaft 110 is rotatably coupled and which houses the rotor 120, a second support member 140 positioned in the gap space 123c and circumferentially supported by the housing 150, and an elastic member 160 that supports the second support member 140 and is circumferentially adhered to both ends of the spring 123.

[0017] Also, according to the present embodiment, mobility including the steering input device 100 can be provided.

[0018] First, referring to FIGS. 10a to 10c, the lean function of the mobility according to the present embodiment will be described in detail.

[0019] FIG. 10a shows a state in which the lean function of the mobility according to the present embodiment is not performed, and for example, it can be in a stopped, straight-ahead, or reverse state.

[0020] FIGS. 10b and 10c show states in which the lean function of the mobility according to the present embodiment is performed. FIG. 10b shows a state in which the vehicle body tilts by the lean function during turning travel, and FIG. 10c shows a state in which the height difference between the left and right wheels is offset by the lean function on a stepped terrain.

[0021] That is, by using the lean function, it is possible to improve driving safety during turning travel, provide a dynamic driving environment for the driver, and also provide a suspension function for absorbing ground steps.

[0022] The mobility according to the present embodiment includes a lean bar 1000 whose both ends are connected to the left and right wheels in order to perform the lean function. Both ends of the lean bar 1000 are connected to the left and right wheels through a linkage structure.

[0023] The mobility according to these embodiments includes a lean actuator, and the lean function is performed by rotating a lean bar by the lean actuator.

[0024] The mobility according to these embodiments includes a steering input device 100 according to these embodiments. The steering input device 100 according to these embodiments is provided in the mobility according to these embodiments and receives steering input from the driver.

[0025] According to one embodiment, the mobility according to this embodiment may further include a steering angle sensor for sensing the rotation angle of the steering axis, a steering actuator for generating steering force to steer the wheels, and an electronic control device that receives rotation angle information of the steering axis from the steering angle sensor and controls the steering actuator.

[0026] A steering wheel is connected to the steering shaft, and the steering input device 100 according to this embodiment can be operated through the driver's operation of the steering wheel. The steering angle sensor senses the rotation angle of the steering shaft and transmits it to the electronic control unit.

[0027] The electronic control unit can control the steering actuator based on information such as the rotation angle of the steering axis received from the steering angle sensor, as well as other information such as vehicle speed and the driver's steering torque.

[0028] Under the control of the electronic control unit, the steering actuator generates steering force for steering the wheels, thereby performing the steering of the mobility according to these embodiments.

[0029] In one embodiment, the steering actuator can steer the front wheels. In this embodiment, both front wheels of the mobility are connected to a lean bar and a lean function can be performed by a lean actuator, and they can also be steered by the steering actuator.

[0030] Next, referring to Figures 1 to 4, the steering input device 100 according to this embodiment includes a steering shaft 110, a rotor 120, a first support member 130, a housing 150, a second support member 140, and an elastic member 160.

[0031] The steering shaft 110 is connected to the steering wheel and rotated by the driver's steering wheel operation. The rotor 120 is coupled to the steering shaft 110 and rotates together with the steering shaft 110. The steering shaft 110 is rotatably coupled to the housing 150. The steering shaft 110 can be coupled to the housing 150 by bearings.

[0032] The housing 150 houses the rotor 120. The housing 150 may include a main housing 151 which is hollow and houses the rotor 120, a cover housing 153 which is coupled to the main housing 151 and to one side of the steering shaft 110, and a sensor housing 152 which is coupled to the other side of the steering shaft 110 and houses the sensor 212 described later.

[0033] The steering input device 100 according to this embodiment can be installed while the main housing 151 is connected to the vehicle body.

[0034] The rotor 120 is equipped with a spring 123. As the steering shaft 110 rotates, the torque generated by the twisting of the spring 123 is supplied to the steering shaft 110 as a reaction torque, improving the driver's steering feel. In addition, the steering wheel, which has been rotated by the torque provided by the spring 123, can be returned to the neutral position.

[0035] A circumferential separation space 123c is formed between one end (see reference numeral 123a) and the other end (see reference numeral 123b) of the spring 123 (see Figure 4).

[0036] The first support member 130 and the second support member 140 are positioned in the separation space 123c formed between the ends of the spring 123 (see Figure 5).

[0037] The first support member 130 is located in the separation space 123c and is circumferentially supported at both ends of the spring 123, and the second support member 140 is located in the separation space 123c and is tightly attached to both ends of the spring 123 by the elastic member 160.

[0038] In other words, the direction in which the first support member 130 and the second support member 140 are supported at one end of the spring 123 and the direction in which they are supported at the other end of the spring 123 are the same.

[0039] Furthermore, since the steering feel provided to the driver must be equal regardless of the direction of rotation of the steering wheel, the ends of the spring 123, the first support member 130 and the second support member 140 are provided symmetrically on both sides.

[0040] As shown in the drawing, the first support member 130 has a load configuration parallel to the steering axis 110 and can support both ends of the spring 123.

[0041] Furthermore, as will be described in detail later, the second support member 140 may include a first support member 141 that is in close contact with one end of the spring 123 and a second support member 142 that is in close contact with the other end of the spring 123.

[0042] The first support 141 and the second support 142 are tightly attached to one end and the other end of the spring 123, respectively, by the elastic member 160.

[0043] The first support member 130 is coupled to the rotor 120 and rotates together with the steering shaft 110, while the second support member 140 is circumferentially supported by the housing 150.

[0044] In other words, when the steering shaft 110 is rotated, the first support member 130 is rotated, but the second support member 140 is not rotated.

[0045] As the steering shaft 110 rotates, the first support member 130 is supported by one or the other end of the spring 123 and rotated, while the other or one end of the spring 123 is supported and fixed by the second support member 140.

[0046] Therefore, the spring 123 twists, providing a reaction torque to the steering shaft 110. The structure for providing reaction torque due to the twisting of the spring 123 will be described in detail later.

[0047] Referring to Figure 2 for a more detailed view, the steering input device 100 according to this embodiment may further include a damper 211 coupled to the steering shaft 110 and the housing 150.

[0048] The damper 211 can be coupled to the end of the steering shaft 110 and to the sensor housing 152. The damper 211 provides rotational damping to the steering shaft 110, thereby improving the steering feel.

[0049] Furthermore, according to one embodiment, the steering input device 100 according to these embodiments may further include a sensor 212 for sensing the rotation angle of the steering shaft 110.

[0050] The sensor 212 can sense the rotation angle of the steering shaft 110 and transmit the rotation angle information to an electronic control unit that controls the steering actuator, which generates steering force to steer the wheels.

[0051] In other words, the steering shaft 110 of the steering input device 100 in these embodiments may not be mechanically connected to the wheel being steered. The electronic control unit can control the steering actuator based on rotation angle information sensed by the sensor 212, and information sensed by other sensors, such as vehicle speed and the driver's steering torque.

[0052] Referring to Figure 3 for a more detailed view, according to one embodiment, the rotor 120 may include a first rotor 121 to which the first support member 130 is coupled, and a second rotor 122 to which the spring 123 is attached.

[0053] According to one embodiment, the first rotor 121 can be coupled to the steering shaft 110 and its serrations. Thus, the rotor 120 and the steering shaft 110 can be fixed in the circumferential direction and rotate together.

[0054] In one embodiment, a first stopper 121a is formed on the first rotor 121, and a second stopper 153a is formed on the housing 150 that can be circumferentially supported by the first stopper 121a. The rotation of the steering shaft 110 is stopped by the first stopper 121a being supported by the second stopper 153a.

[0055] According to one embodiment, the first stopper 121a is formed on one axial side of the first rotor 121, and the first support member 130 can be coupled to the other axial side of the first rotor 121.

[0056] The second stopper 153a is formed on the inner surface of the sensor housing 152, and the first stopper 121a and the second stopper 153a are formed on the surfaces of the first rotor 121 and the sensor housing 152 that face each other. The first support member 130 can be coupled to the other axial side of the first rotor 121, that is, the side opposite to the surface on which the first stopper 121a is formed.

[0057] In one embodiment, the spring 123 can be attached to the outer surface of the second rotor 122. The second rotor 122 can be coupled to the other axial side of the first rotor 121, i.e., the surface to which the first support member 130 is attached.

[0058] Therefore, the first rotor 121 and the second rotor 122 rotate together. The spring 123 is attached to the outer surface of the second rotor 122, and as will be described later, both ends are bent so that they protrude radially from the outer surface of the second rotor 122.

[0059] According to one embodiment, the second rotor 122 may include a first bush 221 coupled to the first rotor 121 and having a first projection 221a formed on its outer surface, which is supported by a spring 123 on one axial side, and a second bush 222 coupled to the first bush 221 and having a second projection 222a formed on its outer surface, which is supported by a spring 123 on the other axial side.

[0060] The first bush 221 and the second bush 222 are connected axially, and the spring 123 is positioned between the first projection 221a and the second projection 222a on the outer surfaces of the first bush 221 and the second bush 222 (see Figure 2).

[0061] Referring to Figures 4 and 5 in detail, according to one embodiment, one end and the other end of the spring 123 are bent to extend radially, and a separation space 123c can be formed. Both ends of the spring 123 are separated in the axial direction and form a separation space 123c in the circumferential direction.

[0062] The first support member 130 is located in the separation space 123c and supports both ends of the spring 123, and the second support member 140 is located in the separation space 123c and is in close contact with both ends of the spring 123 by the elastic member 160. That is, one end and the other end of the spring 123 are supported by the first support member 130 and the second support member 140, which are located in the separation space 123c on opposite sides to each other.

[0063] When the rotor 120 rotates to one side in the circumferential direction together with the steering shaft 110, the first support member 130 rotates while being supported by one end of the spring 123.

[0064] Incidentally, the other end of the spring 123 is supported and fixed by a second support member 140 which is circumferentially supported and fixed to the housing 150, and is therefore fixed and unable to rotate. As a result, torsion occurs in the spring 123, providing a reaction torque to the steering shaft 110.

[0065] Conversely, if the rotor 120 rotates to the other side in the circumferential direction along with the steering shaft 110, the first support member 130 rotates while being supported by the other end of the spring 123. Since one end of the spring 123 is fixed and cannot be rotated by the second support, twisting of the spring 123 occurs, providing a reaction torque to the steering shaft 110.

[0066] If both ends of the spring 123 cannot be simultaneously supported by the first support member 130 and the second support member 140, the driver's steering feel will be reduced.

[0067] In other words, if, in the neutral position of the steering wheel, both ends of the spring 123 are supported only by the first support member 130, and there is a gap between both ends of the spring 123 and both sides of the second support member 140, then when the steering shaft 110 rotates circumferentially, twisting of the spring 123 does not occur and reaction torque cannot be provided until the ends of the spring 123 are supported by the second support member 140, resulting in a decrease in steering feel.

[0068] Alternatively, if, in the neutral position of the steering wheel, both ends of the spring 123 are supported only by the second support member 140, and there is a gap between both ends of the spring 123 and both sides of the first support member 130, the steering shaft 110 will spin freely until the ends of the spring 123 are supported by the first support member 130, thus reducing the steering feel.

[0069] Alternatively, if, in the neutral position of the steering wheel, neither end of the spring 123 can be supported by either the first support member 130 or the second support member 140, it is natural that the driver's steering feel will be reduced.

[0070] Therefore, in order to provide the driver with a high level of steering feel, both ends of the spring 123 must be simultaneously supported by the first support member 130 and the second support member 140.

[0071] Figure 5 shows the state in the neutral position where both ends of the spring 123 are simultaneously supported by the first support member 130 and the second support member 140. Then, Figure 6 shows the state where the steering shaft 110 is rotated counterclockwise in the drawing from the neutral position, with one end of the spring 123 supported and fixed by the second support member 140 and the other end of the spring 123 supported and rotated by the first support member 130.

[0072] As shown in Figure 5, in the neutral position, both ends of the spring 123 are simultaneously supported by the first support member 130 and the second support member 140. As shown in Figure 6, when the steering shaft 110 is rotated, one end or the other end of the spring 123 remains stationary due to the second support member 140, even when the first support member 130 is rotated.

[0073] Therefore, as soon as the driver rotates the steering wheel to the neutral position, the spring 123 immediately twists, providing a reaction torque.

[0074] If there is a gap between the end of the spring 123 and the second support member 140, the steering feel will be reduced because the spring 123 will not twist before the driver rotates the steering wheel by approximately that gap. Through such a structure, the steering input device 100 according to these embodiments can provide the driver with a high level of steering feel.

[0075] According to one embodiment, the second support member 140 may include a first support 141 that is in close contact with one end of the spring 123 and a second support 142 that is in close contact with the other end of the spring 123.

[0076] The first support member 130 is a single unit and is simultaneously supported at both ends of the spring 123, while the second support member 140 is separated by the first support 141 and the second support 142 and can be tightly attached to one end and the other end of the spring 123, respectively, by the elastic member 160.

[0077] In other words, one end of the spring 123 can be simultaneously supported by the first support member 130 and the first support member 141, and the other end of the spring 123 can be simultaneously supported by the first support member 130 and the second support member 142.

[0078] Referring to Figures 2 and 7 in detail, according to one embodiment, a slit 154 can be formed in the housing 150 into which the first support 141 and the second support 142 are inserted so as to be movable in the axial direction.

[0079] The first support 141 and the second support 142, inserted into the slit 154, are movable axially along the slit 154, but are held in close contact with one end and the other end of the spring 123, respectively, by the elastic member 160.

[0080] According to one embodiment, the elastic member 160 can be provided between the first support 141 and the second support 142. The elastic member 160 provides an axially outward elastic force between the first support 141 and the second support 142, thereby causing the first support 141 and the second support 142 to be in close contact with one end and the other end of the spring 123, respectively.

[0081] In one embodiment, the elastic member 160 may be a coil spring. The first support 141 and the second support 142 have projections formed on them for insertion into the coil spring, and the coil spring can be joined by having both ends sandwiched between the projections of the first support 141 and the second support 142.

[0082] Referring to Figure 8 for a more detailed view, according to one embodiment, the first support 141 and the second support 142 can be formed so that their width narrows along the axial direction. Inclined surfaces can be formed on both sides of the first support 141 and the second support 142 so that their width narrows along the axial direction.

[0083] The first support 141 and the second support 142 may be formed with their axial inward and outward orientations, that is, their widths may decrease as they move further apart from each other. Thus, by receiving the elastic force of the elastic member 160 in the axial outward direction, they can naturally come into close contact with one end and the other end of the spring 123.

[0084] According to one embodiment, the first support 141 and the second support 142, which are in close contact with one end and the other end of the spring 123, can be fixed to the housing 150 by a fixing member 902.

[0085] In other words, the first support 141 and the second support 142 are tightly attached to both ends of the spring 123 by the elastic member 160, and one end and the other end of the spring 123 are simultaneously supported by the first support member 130 and the second support member 140. After that, the first support 141 and the second support 142, which are inserted into the slit 154, can be fixed to the housing 150 by the fixing member 902.

[0086] Referring to Figures 9A and 9B, we will examine in detail an example of a method in which the first support 141 and the second support 142 are in close contact with both ends of the spring 123 in the steering input device 100 according to this embodiment.

[0087] First, in the initial assembly state, the elastic member 160 is compressed by the jig 901 connected to the first support 141 and the second support 142. Then, when the jig 901 is removed, the elastic force of the elastic member 160 moves the first support 141 and the second support 142 outward in the axial direction, causing them to come into close contact with one end and the other end of the spring 123, respectively.

[0088] Through this process, both ends of the spring 123 can be easily supported simultaneously by the first support member 130 and the second support member 140. Subsequently, the first support member 141 and the second support member 142 can be fixed to the housing 150 with the fixing member 902.

[0089] According to one embodiment, after the first support 141 and the second support 142 are fixed to the housing 150 by the fixing member 902, the elastic member 160 can be removed.

[0090] A steering input device having such a shape and a mobility device including the same can be provided, which has a compact structure and can improve the driver's steering feel.
